Great 2D artwork examples

It occurs to me that it should be possible to draw great 2D art using OpenGL since technically you have control over all the pixels. I would think that 2D cartoon figures would be possible, for example, but I'm having some difficulty finding quality examples online, so perhaps it is not as common or feasible as I thought.

Are 2D drawings with good details (and anti-aliased) something that many are doing here, or know of some good examples anywhere?
